The reasons for more urine foam in the morning are kidney disease, normal physiological phenomena, etc., as follows: 1. Kidney disease: When urine foam increases significantly, like laundry detergent foam or beer foam, you should be alert to kidney-related diseases, such as nephritis, nephrotic syndrome, diabetic nephropathy, etc. These kidney diseases, which can lead to an increase in urine protein, can cause a significant increase in urine foam. You can get a preliminary understanding of the condition by checking the urine routine, and if the urine test is normal, there is no need to worry. Usually pay attention to drink more water and urinate more often. If there is positive urine protein, it means that kidney-related diseases have occurred, and treatment plans need to be formulated according to the specific condition and cause; 2. Normal physiological phenomenon: urine contains many metabolic wastes of the human body, and these substances can change the surface tension of urine, so foam in urine will appear.
